The Retroacetabular Angle Determines the Safe Angle for Screw Placement in Posterior Acetabular Fracture Fixation
Table 1
Example of the computed allowance angles for each one mm of medialization of screw site in the posterior acetabular wall for a patient with a retroacetabular angle of 42 degrees and a retroacetabular tangent of 32 mm as it appears in our computer program.
